(01. 29-448) Fig. 8 is a perspective view of a yoke-shaped coupling block or housing which I employ; and, Fig. 9 shows the method of attaching the block plate attached to the stringer.

In Figs. 1 and 2 of the drawing, I have shown for the purpose of illustrating one use of .my invention one end portion of the tapes l and H of a separable fastenen'to the beadededges Illa, I id of which are secured the coupling links l2.

of the fastener by a slider i3 movable longitudinally of the fastener stringers in coupling and uncouplingsaid links. The slider has top and bottom plates joined by a V-shaped body It at the enlarged end portion of the slider as in other devices of this kind, which body l4 also forms the diverging channels through which the separated links 12 pass. At I31: I have shown the reduced end portion of the slider having the single channel into which the diverging channels extend as in other sliders of this class.

In Figs. 1 and 2 of the drawing, I have also shown at I? a detachably coupled end stop device, by means of which the end portions of the tapes l0, ll, may be detached one from the other to permit the separation of the garment or other parts to which the fastener device is secured in the use of devices of this kind on such garments as jackets, wind-breakers and the like or in any tachable end stops, the several parts of which have relatively long bearing or engaging surfaces on the tapes or stringers, and further wherein the separate parts are interlocked with each other to prevent relative movement of the parts; a further object being to provide an end stop consisting of preformed parts which may be formed -from stampings or die castings and which when assembled will be interlocked one with the other and which includes means in addition to the mounting plates for retaining the parts against displacement from the tapes or stringers; and with these and other objects in view, the invention consists in an end stop of the class and for the purpose specified, which is constructed in parts and in assemblage in accordance with the method. hereinafter more fully described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which: I

two stringers of the fastener for any purpose substantially similar mounting or coupling plates l1 and iii are separately formed and are then assembled in the manner hereinafter described.

construction and these parts are simply'formed lefts and rights to adapt their mounting to the stringers l0 and H, and the brief description of one plate will apply to both. In Figs. 3, 4 and 5 of the drawing, I have shown the plate 16 and have indicated the manner 0t attaching the same to'the tape l0. As shown, the plate It is preferably formed from a sheet metal blank which is cut out to form side plate portions IS and 20 having apertures 2i adapted to register with each other. When the plate It is secured'to the support I 0 as shown in Fig. 5, one side edge of the side plate I8 is provided with a flange 22 and the other side edge with 9. prong 23 and the curved wall 24 which joins the plates l9 and It is cut or housing to one of the stringers or the bar and The. links are interlocked and separated in the usel6, i6a, two substantially similar coupling bars i'l, Ila. and a coupling block. or housing I8. In constructing the end stop device IS, the parts 16, I

Each of the parts l6, Ilia is of the same general other uses where it is desirable to separate'the whatever. The end stop device l 5 consists of two with the plates by reason of the inwardly proout as seen at 25 to form 'a key receiving portion as later described. I

After the plates I6, I611 have been formed and shaped in the manner illustrated in Fig. 3 of the drawing, the trimmed end portion of the tapes is placed upon the inner surface of the plate I9 with the prong 23 passing upwardly through the tape as-may be seen in Fig. 4 of the drawing, after which the plate 20 is then folded downwardly upon the tape I0, and the flange 22 and prong 23 are folded inwardly upon the plate 20 in the manner shown in Fig. 5 of the drawing, it'being understood that the curved wall 24 joining the plates I9 and 20 extends around the beaded edge Illa of the tape, and it is preferred that the parts be securely pressed together and upon the tape to retain the same against displacement therefrom.

After the coupling or mounting plates I6, Iia

have been secured to the tapes of the stringers,

' the next step in the method of forming the complete device consists in applying the channeled bars I1, I1a thereto. Two'of these bars are shown in detail in Fig. 6 of the drawing, and aside from the provision of a projecting tongue 26 on one bar I1 and the provision of a recess or aperture 21 on the bar I1a, note Fig. 2 of the drawing, the two bars I1, I11: are of the same constructionand are eachprovided with a longitudinal channel 28 to receive the beaded edge of the stringers. The channeled structure forms side walls 29 and 30 and the surfaces of the channel 28- are provided with longitudinally spaced ribs or teeth 3I arranged at one end portion of the bar which are adapted to engage the fabric of the tapes III, II to aid'in retaining the bars 'I1,'I1a against longitudinal movement upon the stringers, and in like manner, to aid in securing the attaching plates I6, I61: to the stringers through the interlocking engagement of the bars jecting members 32 engaging the cut out or recess portions 25 of the plates I 8, Iia as is indicated in Fig. 2 of the drawing in the coupling of the bar I1a with the plate I90.

The bars I1 and I1a are normally in the position shown in Fig. 6 of the drawing or with the walls 29 and 30 separated so as tofacilitate the mounting of the bars upon thefplates I9, "a

and the stringers I8 and II.. A r placing the bars in position thereon to bring the projections 32 into registering alinement with the-recesses 25, the bars are compressed upon the plates and tapes in the manner shown in'Fig. 7 to securely 56 couple the parts together and to the tapes II and II. The inner adJacent surfaces of the bars I1, I1a are straight and. preferably beveled to a slight degreev at one end thereof as indicated at 33 to facilitate the coupling and uncoupling of the bar I1 with the housing I8 in attaching and detaching the stringers. I

It is preferred that the channeled bars orrods I1, I1a be formed from die castings so asfto economize and simplify the production thereof, it

' to its associated parts.

The block- I3 consists of an elongated-yokeshaped body, the side walls 34 and 35 of which have rounded-outer-surfaces and the side edges of these walls terminate in inwardly extending flanges 36 which are spaced apart to form channels 31 to receive the plates I6, Ilia. The crosshead 38 of the block I8 joins the side plates 34 and 35. The inner surface 39 of the crosshead 38 serves as a stop wall limiting inward movement of the bar I1 as is indicated in Fig 2 of the drawing. The block I8 is secured to the bar I1a only, the bar I1 and the associated parts being attachable and detachable with respect to the block. The walls 34, 35.01 the block I8 as formed are slightly diverged, and the block I8 is slid onto the bar I1a over the end of the tape II;

' and when moved into its innermost position, the

walls 34 and 35 are compressed upon the plate I64: and bar Na, and a hole 40 is drilled or otherwise formed through the walls 34, 35 of the block I8, through'the bar Na, and through the plate Ilia and the tape II, and a rivet or coupling pin 4i, note Figs. 1 and 2, is then passed through the several parts and riveted over to secure said parts together and to. firmly couple the block I8 The side flanges 31 are arranged directly upon the outer edges of the walls 29 and 30 and inwardly of the flange 22, and the inner adjacent surfaces of the walls 34.

and 35 rest upon the upper and lower surfaces of the bar I la.

In practice, the bar I1 will be madeslightly smaller in its dimensions to permit free movement of said bar into and out of the channel which is indicated at 42 in Fig. 9 of the drawing and which is formed within the block I8 at one side of the bar I11: and the flanges 31 to the left serve to engage the outer edges of the walls 29 and 39 of the bar I1 to securely retain this bar against displacement from the block I8 when the parts are secured together in the manner clearly seen in Figs. 1 and 2 of the drawing. The several parts of the detachably coupled end stop I! maybe plated or otherwise treated to give the same the desired finish and appearance consistcut with that of the appearance of the links I2 employed on the stringers.

', with the several parts of the device l5 assembled in the manner or in accordance with the use. In coupling the detachable parts of the device, the slider I3 is first brought into the position shown in Fig. 2 of the drawing and the bar I1 is thenpassed through the'slider and into the channel 42 and moved into the position shown in Fig. 2, iii-which position, the projecting tongue 26 enters the recess 21, after which the slider I3 is moved outwardly in the manner partially illustrated in Fig. 1 of. the drawingin the operation of coupling the stringers together. Thus, when the separate parts of the fastener are coupled together as shown in Fig. 1, the detachably coupled ends of the stringers will be securely retained against displacement or detachment as long as the links I2 remain coupled together. In this connection, it will of course be understood that the bars or rods I1, I1a project beyond the inner end of the coupling block I 8, and the re-.

duced end I311 01' the slider is adapted to extend onto said projecting ends of said bars when it is desired to uncouple or separate the stringers. By moving the slider into this position which is 'ofthe block I8 as shown in Fig. 9. These flanges method above deiined,the device is then ready' for shown in Fig. 2 of the drawing, the bar I1 may be withdrawn from the block I8 through the 2,115,369 slider l3, thus permitting the separation 01 the stringers lo and l I one from the other.

The projecting tongue 26, in addition to aiding in securing the bars l1, l'la against relative movement when coupled together, also provides means for preventing movement of the slider l3 in the operation of closing the fastener until the tongue i6 has entered the recess 21. When the tongue is in proper position, the stringers may be performed without danger of slippage or movement of the bar l1 and its associated stringer with respect to the companion bar 'ila and the housing i8 thereof, thus facilitating the coupling of the fastener stringers.

The separate pairs of parts it, Ilia, l1, .I'la and i8 will be preformed by the tools, dies or other means provided for the construction thereof, and these parts will be mounted or assembled upon the stringer tapes in a successive series of operations in the manner above defined. By constructing the separate parts in the manner disclosed, a. very simple and yet, a very positive means is provided for securing the parts to the stringer tapes in such a way much as possible the stresses and strains to which the parts are subjected, and to avoid the possibility of. detachment of the parts from the stringer tapes when excessively strained.- The teeth or projections 3i aid materially in this reinforcement of the mounting upon the tape and extend the engaging or gripping area of the parts to a largedegree over the surface of the tapes including the beaded edges thereof.

-The' apertures 21 are provided for certain reinforced mountings to garments or other articles in connection with which the fasteners are .em-

. ployed; and when such mountings or attachments are not essential, the plates 16, "5a may be materially reduced in size, or in fact, may be confined to portions engaging the beaded edge por-. tlons of the mounting tapes. In some uses of the invention where the stress or; strain upon the end stops is relatively light, the mounting plates or their equivalent may be dispensed with entirely and the bars l1 and lid alone employed directly upon the tapes, the same being shaped or charof Fig. 2 of the drawing, .diameters of said acterized to fit the tapes. In this connection, it will be understood that the bores or channels 28 on the portions of the bars l1, "a that project beyond the block i8 are of less diameter than the portions or sections of. said bore which engage the plates l6, lfia as may be seen at the right in which the larger bores are designated by the reference character 28a. The illustrations in the accompanying drawing trate the details of construction.

When the slider is moved upon the projecting ends of the bars l1, Ila, the transverse V s haped portion l4 of the slider in separating the end links also serves to lock the bar I! so as to move the projecting tongue 26 out of the recess or aperture 21, permitting the free release of the bar I! and its associated stringer in the separation of the stringer. At the same time, this position of the parts facilitates the free insertion of. the bar I! into the position shown in Fig. 2 and in moving the slider i3 into the position shown 1, the projecting end portion of the bar i1 is moved in the direction projecting tongue 26 into the recess or aperture 2L Having the operation of coupling as to eliminate as e ers byfolding and compressing the r are all enlarged and exaggerated as to size in order to-more clearly illusof the bar Ila and the fully described my invention, what I claim as new and desire to secure by Letters I Patent, is:
